Write each fraction as a percent.
$2 over 11$

검증된 단계별 안내

Understand that to convert a fraction to a percent, you first convert the fraction to a decimal by dividing the numerator by the denominator.

Divide 2 by 11 to get the decimal equivalent:

\frac{2}{11} = ?

(do not calculate the exact decimal here, just set up the division).

Once you have the decimal form, multiply it by 100 to convert it to a percent:

\(\text{Decimal}\) \(\times\) 100 = \(\text{Percent}\)

Add the percent symbol (%) to the result to indicate that it is a percentage.

Summarize the process: fraction → decimal (by division) → multiply by 100 → add % symbol.
